Description

Technical Field

[0001] This utility model relates to the field of toys, and in particular to a high shock-absorbing toy tank. Background Technology

[0002] Tank-shaped toys are popular among consumers due to their high level of realism and combination of aesthetic appeal and playability, and are widely used in children's toys, military model collections, and other fields.

[0003] Currently, similar toy battle vehicles on the market either have rigid connections between the wheels and the vehicle body without independent shock absorption mechanisms, resulting in severe bumps during driving; or they only have simple shared shock absorption and do not achieve independent transmission for each wheel, or the independent shock absorption and transmission interfere with each other, making it impossible to maintain stable transmission when the wheels adapt to the terrain and perform independent shock absorption.

[0004] While some high-end models attempt to incorporate structures that combine shock absorption and transmission functions, these two aspects are difficult to achieve simultaneously. Either the shock absorption interrupts the transmission, or the transmission structure limits the shock absorption amplitude, failing to replicate the smooth driving and power transmission effects of a real combat vehicle under complex road conditions, significantly reducing simulation accuracy. While some models employing complex structures can achieve both shock absorption and transmission functions, the complex structures require significant installation space, raising the already low-chassis vehicle and compromising simulation accuracy. Furthermore, these structures are cumbersome to assemble, have high production costs, are prone to malfunctions, and long-term use can lead to wheel loosening, transmission failure, and shortened lifespan. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high shock-absorbing toy tank. This high shock-absorbing toy tank can adapt to various terrains and, when crossing various obstacles, each wheel can perform independent movements to adapt to the terrain while maintaining transmission.

[0006] To solve the above technical problems, the following technical solution is adopted:

[0007] A high-shock-absorbing toy tank includes a shell, a body, at least one first wheel assembly, and at least one second wheel assembly. The shell is mounted on the body. Both the first and second wheel assemblies include a rotation drive mechanism capable of driving the wheels, two wheels, and two shock-absorbing mechanisms. The rotation drive mechanism is mounted on the body. Each wheel corresponds to one shock-absorbing mechanism. Each wheel has a steering knuckle, and the steering knuckles of the two wheels are respectively positioned on both sides of the body via corresponding shock-absorbing mechanisms. The steering knuckle is characterized by: a first guide seat arranged laterally with a first guide hole; two second guide seats arranged laterally at the left and right ends of the rotation drive mechanism, each with a second guide hole; the shock-absorbing mechanism includes a coupling shaft, a reset assembly, a first compression spring, and a second compression spring. The first compression spring is positioned in the first guide hole, and the second compression spring is positioned in the second guide hole. One end of the coupling shaft is movably positioned in the first guide hole and connected to the first compression spring, and the other end of the coupling shaft is movably positioned in the second guide hole and connected to the second compression spring; the steering knuckle is connected to the body via the reset assembly.

[0008] The aforementioned high-shock-absorbing toy tanks typically include a remote control for controlling the tank's movements, a battery for power supply, and a control device for receiving signals from the remote control and controlling the tank's movements. The battery and control device are installed separately within the vehicle body. Both the remote control and control device employ a common design for toy cars. When the toy tank moves, the rotating drive mechanism drives the coupling shaft to rotate via the second guide seat, thereby causing the two wheels to rotate synchronously. Because the wheels cooperate with the second guide seat of the rotating drive mechanism via the coupling shaft, each wheel can operate independently. Therefore, when the tank travels on complex terrain, each shock-absorbing mechanism can operate independently according to the force on its corresponding wheel, without affecting other wheels. During movement, the wheels simultaneously drive the reset assembly and the coupling shaft via the steering knuckle and the first guide seat. The coupling shaft can move along the first and second guide seats and compress the compression spring, thus adapting to changes in wheel position while maintaining transmission. When the wheels return to the normal road surface, the reset assembly can reset the wheels, and the coupling shaft can also return to its normal position under the action of the compression spring. This high-shock-absorbing toy vehicle can adapt to various terrains, and when crossing different obstacles, each wheel can perform independent movements to adapt to the terrain while maintaining transmission.

[0009] In a preferred embodiment, two guide notches are respectively formed on the sidewalls of the first and second guide seats along the length direction, and the two guide notches are positioned correspondingly. Two first guide posts matching the guide notches are respectively provided at both ends of the connecting shaft. The first guide posts are located in the corresponding guide notches, and the ends of the connecting shaft are hinged to the first guide posts. By setting the guide notches and first guide posts, the connecting shaft can be radially limited, allowing the rotation drive mechanism to continuously drive the wheel to rotate via the connecting shaft. Simultaneously, since the connecting shaft will displace and oscillate when the wheel swings up and down, in this case, the connecting shaft can oscillate accordingly along the guide notches via the first guide posts. Typically, the diameters at both ends of the connecting shaft are much smaller than the inner diameter of the corresponding guide seats, providing space for the oscillation of the connecting shaft.

[0010] In a preferred embodiment, the first wheel assembly further includes a steering mechanism mounted on the vehicle body. The power output end of the steering mechanism is connected to the steering knuckle of the wheel in the first wheel assembly. The steering mechanism can employ a structure combining a servo motor, a servo arm, and a connecting rod (typically, the connecting rod consists of a three-section structure, including a universal joint and two connecting sections connected by the universal joint, and each connecting section is connected to the servo arm and the steering knuckle respectively; this structure allows the connecting sections to swing correspondingly through the universal joint without disengaging when the wheel moves up and down). Alternatively, it can employ a structure of a motor and a transmission gear set, where steering is achieved by controlling the forward and reverse rotation of the motor to drive the transmission gear set.

[0011] In a further preferred embodiment, the first wheel assembly is disposed at the front of the vehicle body, and the second wheel assembly is disposed at the rear of the vehicle body.

[0012] In a further preferred embodiment, the reset component of the shock absorber mechanism of the first wheel assembly includes a guide sleeve, a third compression spring, a second guide post, and a first swing arm. The guide sleeve is mounted on the vehicle body, the third compression spring is disposed within the guide sleeve, and the second guide post is movably disposed within the guide sleeve. The upper end of the third compression spring is connected to the inner top wall of the guide sleeve, and the lower end of the third compression spring is connected to the second guide post. The lower end of the second guide post is hinged to the steering knuckle of the corresponding wheel. One end of the first swing arm is hinged to the lower surface of the vehicle body, and the other end of the first swing arm is connected to the lower end of the steering knuckle of the wheel. When the wheel reaches its highest point and is compressed, the first swing arm swings accordingly. The steering knuckle compresses the third compression spring through the second guide post. After the wheel passes its highest point, the third compression spring pushes the second guide post to reset the wheel. Since the first wheel assembly has a steering mechanism, by adopting the above structure for the reset component, better support can be provided for the wheel and steering knuckle to ensure the overall stability of the first wheel assembly. Furthermore, the guide sleeve mounted on the vehicle body can adopt a shape that matches the hydraulic shock absorbers in a real vehicle, improving the simulation accuracy.

[0013] In a further preferred embodiment, the reset component in the shock absorber mechanism of the second wheel assembly includes a torsion spring and a second control arm. One end of the second control arm is hinged to the steering knuckle of the corresponding wheel, and the other end of the second control arm is hinged to the side wall of the vehicle body via a pivot. The torsion spring is sleeved on the pivot, with one end connected to the vehicle body and the other end connected to the second control arm. In real vehicles, the rear of the vehicle body is usually a loading space, so the installation space for the second wheel assembly is relatively small, making it impossible to use the same structure as the reset component in the first wheel assembly. Therefore, a structure combining a second control arm and a torsion spring is adopted, which can be installed on the side of the vehicle body, thus saving space while achieving the reset function. When the wheel is compressed, the second control arm twists the torsion spring under the action of the steering knuckle. After the wheel passes the high point, the second control arm can reset the wheel under the action of the torsion spring.

[0014] In a further preferred embodiment, the number of the first wheel assembly and the second wheel assembly are both two.

[0015] Among the aforementioned rotary drive mechanisms, the rotary drive mechanism in the wheel assembly at the foremost side of the vehicle body includes a drive motor and a drive gearbox. The drive motor is mounted on the vehicle body, and its power output shaft is connected to the power input end of the drive gearbox. The drive gearbox has power output ends on its left and right sides, and each of the two power output ends is connected to a corresponding second guide seat. The rotary drive mechanisms in the wheel assemblies at other positions on the vehicle body include drive gearboxes. Each drive gearbox can be configured using two bevel gears, a transverse drive shaft, and a longitudinal drive shaft. The two bevel gears mesh with each other at a 90° angle and are mounted on two drive shafts. The two ends of the transverse drive shaft are connected to the left and right second guide seats, respectively. The rear end of the longitudinal drive shaft of the front drive gearbox is connected to the front end of the longitudinal drive shaft of the rear drive gearbox (wherein, the drive shaft at the front of the foremost drive gearbox can be the power output shaft of the drive motor).

[0016] The beneficial effects of this invention are that this high shock-absorbing toy vehicle can adapt to various terrains, and when crossing various obstacles, each wheel can perform independent movements to adapt to the terrain while maintaining transmission. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figure 1-4 The toy tank with high shock absorption shown includes a shell 1, a body 2, two first wheel assemblies 3, and two second wheel assemblies 4. The shell 1 is mounted on the body 2. Each of the first wheel assembly 3 and the second wheel assembly 4 includes a rotation drive mechanism 5 capable of driving the wheels 6 to rotate, two wheels 6, and two shock absorption mechanisms 7. The rotation drive mechanism 5 is mounted on the body 2. The wheels 6 correspond one-to-one with the shock absorption mechanisms 7. Each wheel 6 is provided with a steering knuckle 601. The steering knuckles 601 of the two wheels 6 are respectively set on both sides of the body 2 through the corresponding shock absorption mechanisms 7. The steering knuckle 601 is provided with a first guide seat 6011 arranged laterally, and the first guide seat 6011 has a first guide hole. The left and right ends of the rotation drive mechanism 5 are respectively provided with two horizontally arranged second guide seats 501, and the second guide seats 501 have second guide holes; the shock absorption mechanism 7 includes a connecting shaft 701, a reset assembly 702, a first compression spring 703 and a second compression spring 704. The first compression spring 703 is disposed in the first guide hole, the second compression spring 704 is disposed in the second guide hole, one end of the connecting shaft 701 is movably disposed in the first guide hole and connected to the first compression spring 703, and the other end of the connecting shaft 701 is movably disposed in the second guide hole and connected to the second compression spring 704; the steering knuckle 601 is connected to the vehicle body 2 through the reset assembly 702.

[0023] The aforementioned high shock-absorbing toy tank also includes a remote control for remotely controlling the tank's movements, a battery for powering the tank, and a control device for receiving signals from the remote control and controlling the tank's movements. The battery and control device are respectively installed in the vehicle body 2. Both the remote control and the control device adopt the general design of toy cars. When the toy tank moves, the rotating drive mechanism 5 drives the connecting shaft 701 to rotate via the second guide seat 501, thereby driving the two wheels 6 to rotate synchronously. Since the wheels 6 cooperate with the second guide seat 501 of the rotating drive mechanism 5 via the connecting shaft 701, each wheel 6 can operate independently. Therefore, when the tank moves on complex terrain, each shock absorber 7 can operate independently according to the force on the corresponding wheel 6 without affecting other wheels 6. During operation, the wheels 6 drive the reset assembly 702 and the connecting shaft 701 simultaneously via the steering knuckle 601 and the first guide seat 6011. The connecting shaft 701 can move along the first guide seat 6011 and the second guide seat 501 and compress the compression spring, thereby adapting to the position changes of the wheels 6 while maintaining transmission. When the wheels 6 return to the normal road surface, the reset assembly 702 can drive the wheels 6 to reset. At this time, the connecting shaft 701 can also return to its normal position under the action of the compression spring. This high-shock-absorbing toy vehicle can adapt to various terrains, and when crossing different obstacles, each wheel 6 can both perform independent movements to adapt to the terrain and maintain transmission.

[0024] Two guide notches 561 are respectively provided on the side walls of the first guide seat 6011 and the second guide seat 501 along the length direction, and the two guide notches 561 are positioned correspondingly. Two first guide posts 7011 matching the guide notches 561 are respectively provided at both ends of the connecting shaft 701. The first guide posts 7011 are located in the corresponding guide notches 561, and the ends of the connecting shaft 701 are hinged to the first guide posts 7011. By setting the guide notches 561 and the first guide posts 7011, the connecting shaft 701 can be limited radially, so that the rotation drive mechanism 5 can continuously drive the wheel 6 to rotate through the connecting shaft 701. At the same time, since the connecting shaft 701 will have displacement and swing when the wheel 6 swings up and down, in this case, the connecting shaft 701 can swing accordingly along the guide notches 561 through the first guide posts 7011. Typically, the diameters at both ends of the connecting shaft 701 are much smaller than the inner diameters of the corresponding guide seats, which provides space for the swing of the connecting shaft 701.

[0025] The first wheel assembly 3 also includes a steering mechanism 8, which is mounted on the vehicle body 2. The power output end of the steering mechanism 8 is connected to the steering knuckle 601 of the wheel 6 in the first wheel assembly 3. The steering mechanism 8 adopts a structure in which a servo motor 801, a servo arm 802, and a connecting rod 803 cooperate (the connecting rod 803 consists of a three-section structure, including a universal joint 8031 ​​and two connecting sections 8032, which are connected by the universal joint 8031 ​​and are respectively connected to the servo arm 802 and the steering knuckle 601; this structure allows the connecting sections 8032 to swing correspondingly through the universal joint 8031 ​​when the wheel 6 moves up and down without disengaging).

[0026] The first wheel assembly 3 is located at the front of the vehicle body 2, and the second wheel assembly 4 is located at the rear of the vehicle body 2.

[0027] The reset assembly 702 in the shock absorber mechanism 7 of the first wheel assembly 3 includes a guide sleeve 7021, a third compression spring (not visible in the figure), a second guide post 7022, and a first swing arm 7023. The guide sleeve 7021 is mounted on the vehicle body 2. The third compression spring is disposed in the guide sleeve 7021. The second guide post 7022 is disposed in the guide sleeve 7021 and can move up and down. The upper end of the third compression spring is connected to the inner top wall of the guide sleeve 7021, and the lower end of the third compression spring is connected to the second guide post 7022. The lower end of the second guide post 7022 is hinged to the steering knuckle 601 of the corresponding wheel 6. One end of the first swing arm 7023 is hinged to the lower surface of the vehicle body 2, and the other end of the first swing arm 7023 is connected to the lower end of the steering knuckle 601 of the wheel 6. When wheel 6 reaches its highest point and is compressed, the first control arm 7023 swings accordingly. The steering knuckle 601 compresses the third compression spring via the second guide post 7022. After wheel 6 passes its highest point, the third compression spring pushes the second guide post 7022 to reset wheel 6. Since the first wheel assembly 3 has a steering mechanism 8, to ensure the overall stability of the first wheel assembly 3, the reset assembly 702 adopts the above structure, which provides better support for wheel 6 and steering knuckle 601. Furthermore, the guide sleeve 7021 on the vehicle body 2 can adopt a shape that matches the hydraulic shock absorbers in a real vehicle, improving the simulation accuracy.

[0028] The reset component 702 in the shock absorber mechanism 7 of the second wheel assembly 4 includes a torsion spring (not shown in the figure) and a second swing arm. One end of the second swing arm is hinged to the steering knuckle 601 of the corresponding wheel 6, and the other end of the second swing arm is hinged to the side wall of the vehicle body 2 via a pivot. The torsion spring is sleeved on the pivot, and one end of the torsion spring is connected to the vehicle body 2, while the other end of the torsion spring is connected to the second swing arm. In real vehicles, the rear of the vehicle body 2 is usually a loading space, so the installation space for the second wheel assembly 4 is relatively small. It is not possible to use the same structure as the reset component 702 in the first wheel assembly 3. Therefore, a structure combining the second swing arm and the torsion spring is adopted, which can be set on the side of the vehicle body 2, thereby saving space while performing the reset function. When the wheel 6 is compressed, the second swing arm twists the torsion spring under the action of the steering knuckle 601. After the wheel 6 passes the high point, the second swing arm can reset the wheel 6 under the action of the torsion spring.

[0029] Among the aforementioned rotating drive mechanisms 5, the rotating drive mechanism 5 in the wheel assembly at the foremost side of the vehicle body 2 includes a drive motor (not visible in the figure) and a drive gearbox. The drive motor is mounted on the vehicle body 2, and the power output shaft of the drive motor is connected to the power input end of the drive gearbox. The drive gearbox has power output ends on its left and right sides, and the two power output ends are respectively connected to the corresponding second guide seats 501. The rotating drive mechanisms 5 in the wheel assemblies at other positions of the vehicle body 2 include drive gearboxes. Each drive gearbox can be configured by two bevel gears, a transverse transmission shaft (not visible in the figure), and a longitudinal transmission shaft 502. The two bevel gears mesh with each other at a 90° angle and are respectively mounted on two transmission shafts. The two ends of the transverse transmission shaft are respectively connected to the left and right second guide seats 501. The rear end of the longitudinal transmission shaft 502 of the drive gearbox at the front is connected to the front end of the longitudinal transmission shaft 502 of the drive gearbox at the rear (wherein, the transmission shaft at the front of the drive gearbox at the foremost side is the power output shaft of the drive motor).
